What is an ignition switch and what is its purpose?

Before discussing the wiring diagram, let’s first understand what an ignition switch is and its purpose. The ignition switch is a key-operated electrical switch that controls the power to various components in your vehicle, including the starter, ignition system, and accessories. When you turn the key, the switch sends an electrical signal to the starter to crank the engine and power the ignition system. Once the engine starts, the switch sends power to other components as needed based on your key position.

Components of an ignition switch

An ignition switch has several components that work together to control the power to your vehicle’s components:

Component Description
Key cylinder The part of the switch that the key is inserted into to turn the switch on and off.
Circuitry The wiring and connections that carry the electrical signal from the switch to the various components in your vehicle.
Contacts The parts of the switch that physically make contact with other components to allow power to flow.
Spring-loaded plunger The part of the switch that keeps the contacts apart when the key is in the off position.
